GNAF and Australian addresses

Everything happens somewhere, making location a really useful means for interpreting and analysing information. The one location attribute that is virtually universal across business and government is address. G-NAF or Geocoded National Address File is a database of all the physical addresses in Australia. This dataset is produced by PSMA Australia and is update quarterly. In February 2016, G-NAF was openly released by the Australian Government on data.gov.au together with a second PSMA dataset, Administrative Boundaries. Australia is one of only a few countries in the world to make national geocoded address data openly available.

into over
13 million G-NAF addresses in 13 weeks

9. The G-NAF
production process
does not make any
assumptions about
the quality of the
input addresses.
G-NAF independently
examines and
validates every
candidate address.
Each address is
matched and
validated against the
geospatial region to
which it relates:
state, locality, street
and finally, property.

10. One of the most valuable features of G-NAF is the linkages
created between ‘official’ and ‘in-use’ addresses.

12. A geocoded address opens up a world
of location opportunity
